China Drying Network News Jilin Petrochemical Research Institute took the lead in setting up a mathematical model for sewage treatment in China, scientifically setting sludge return flow rate, dissolved oxygen, and excess sludge volume, etc., and determined appropriate sludge concentration, sludge age, and excess sludge. Emissions and other indicators have achieved research objectives such as improving the quality of effluent water, reducing the amount of sludge, and optimizing aeration, and passed the acceptance of Jilin Petrochemical Company.

this new material and microfiber, non-woven fabric and other substrates combined, processed and prepared, suitable for a variety of industry applications. Silicone leather using solvent-free technology, silicone coating bonded on a variety of substrates to make leather. Belongs to the 21st century development of new material industry. Due to the excellent characteristics of silicone leather itself: flame retardant, weather resistance, anti-fouling, easy to manage, skin friendly is not sensitive, anti-mildew and antibacterial, wear-resistant and durable, safe and non-toxic performance is very outstanding, suitable for hotels, 3C, home, cars, children and other major industries. Compared with traditional leather, silicone leather has advantages in hydrolysis resistance, low VOC, no odor, environmental protection and other properties. In the case of long-term use or placement, PU/PVC and other synthetic leather will make the residual solvent and plasticizer in the leather will be released constantly, which is very bad for people's health. Physical and chemical stability: long-term use no yellowing, no aging, anti-UV; High temperature ultraviolet exposure without odor, no harmful gas production; High and low temperature resistance: low temperature unchanged hard, high temperature is not soft (-50~200℃); Gas permeability, Silicone Material with PU, PVC tens of times of gas permeability; Antibacterial, no mold; Good elasticity, feel comfortable; Excellent biocompatibility.
